Cities across the Northeast mobilized snowplows and airlines canceled thousands of flights Monday as a potentially historic storm pushed its way up the Philadelphia-to-Boston corridor with what forecasters said could be up to 2 feet of snow.

Here in Baton Rouge, New Orleans and Lafayette the weather forecast is quite the opposite.

The National Weather Service said the nor'easter would bring heavy snow, powerful winds and widespread coastal flooding starting Monday and through Tuesday. A blizzard warning was issued for a 250-mile stretch of the Northeast, including New York and Boston.
